Honeywell CPU2-3030D (including ELCM-PCB loop control board and HS-NCM-W high-speed network module) is the complete core component of Honeywell NOTIFIER ONYX series NFS2-3030 intelligent fire alarm control system. It provides centralized fire detection, alarm linkage and network management functions for medium and large-scale premises.
Integrated with dual-core processing, intelligent loop control, high-speed wired networking and long-term log storage, this suite complies with domestic and international fire protection certifications including UL 864, EN 54 and GB 26851. It is widely deployed in high-safety-level scenarios such as commercial complexes, super high-rise buildings, data centers, rail transit, airports and ports.
Core Advantages
High Performance & Large Capacity SupportDual-core ARM Cortex-A9 architecture with 800MHz main frequency; supports up to 3,180 intelligent addressable devices (10 SLC loops, 159 points per loop). Event response time is less than 50 ms, suitable for large-scale campus-level networking.
Intelligent Detection & Low False Alarm RateAdopts VIEW® early warning algorithm and drift compensation technology to distinguish smoke from interference sources. It supports automatic sensitivity testing of detectors and two-level maintenance early warning, with an annual false alarm rate lower than 0.002%.
Modular Redundant DesignCPU, power supply (AMPS-24E), loop board (ELCM-PCB) and network module (HS-NCM-W) all support redundant configuration. Seamless switching is completed within 0.3 seconds upon single-module failure to ensure continuity of critical operations.
Full-network High-speed InterconnectionThe HS-NCM-W module supports NFN high-speed network. Twisted-pair transmission reaches up to 3 km and allows networking with 100 nodes, enabling centralized management across buildings and regions.
Long-term Stable OperationEquipped with 2GB DDR3 + 4GB eMMC storage to retain event logs for 10 years. Wide operating temperature range: -40℃~+70℃ with IP30 protection rating, suitable for industrial and harsh environments.

FAQ
Q: The main panel reports "Loop Trouble". How to troubleshoot?A: ① Check the loop wiring for short circuit or open circuit, and verify the end-of-line (EOL) resistor is normal;② Measure loop voltage with a multimeter (normal value: 24V);③ Replace the ELCM-PCB loop control board for testing;④ Inspect loop devices for damage (e.g., water ingress in detectors).
Q: The HS-NCM-W network module shows "Network Fail" and fails to connect to the network?A: ① Verify twisted-pair wiring (A/B sequence) and ensure transmission distance ≤ 3km;② Confirm unique network node addresses with no conflict;③ Restart the module or replace the HS-NCM-W unit;④ Check main panel network configuration (baud rate / address).
Q: Detectors generate frequent false alarms. How to resolve?A: ① Enable drift compensation for automatic sensitivity calibration;② Clean dust from detectors during monthly maintenance;③ Relocate detectors away from air outlets and fume sources;④ Upgrade the main panel firmware to the latest version.
Q: Event logs are lost after main panel power failure?A: Under normal conditions, logs can be retained for 10 years without loss. If logs disappear:① Check the standby battery (12V28A) and confirm it supplies power during mains failure;② Reboot the panel and reload records via the History menu;③ Contact the manufacturer to inspect the eMMC storage module.
Q: How to configure two-point alarm linkage (e.g., sprinkler activation only when two smoke detectors alarm)?A: Enter Programming → Logic Equation → Create new logic (ZL10) → Set condition as Z1 (Smoke Detector 1) AND Z2 (Smoke Detector 2) → Associate with the sprinkler control module → Save and download configuration. The linkage will only activate when both detectors trigger an alarm simultaneously.
